Ghost Lanterns

The Ghost Lanterns are what the Zebra Brothers use to fight First Squad. Once a month, when the Moon is full, the Ghost Lanterns fill with magic power, which gives the Zebra Brothers abilities to do many things, usually for their benefit, to turn things to their advantage. In "Parrot Castle", the Ghost Lanterns actually burned out, but appeared in subsequent episodes, suggesting they may have more than one set of ghost lanterns.
